ObjectiveTo elucidate the critical role of rehabilitation medical records (including electronic records) in rehabilitation medicine's clinical practice and management, comprehensively analyzed the structure, core content and data standards of rehabilitation medical records, to develop a standardized medical record data architecture and core dataset suitable for rehabilitation medicine and to explore the application of rehabilitation data in performance evaluation and payment. MethodsBased on the regulatory documents Basic Specifications for Medical Record Writing and Basic Specifications for Electronic Medical Records (Trial) issued by National Health Commission of China, and referencing the World Health Organization (WHO) Family of International Classifications (WHO-FICs) classifications, International Classification of Diseases (ICD-10/ICD-11), International Classification of Functioning, Disability and Health (ICF), and International Classification of Health Interventions (ICHI Beta-3), this study constructed the data architecture, core content and data standards for rehabilitation medical records. Furthermore, it explored the application of rehabilitation record summary sheets (home page) data in rehabilitation medical statistics and payment methods, including Diagnosis-related Groups (DRG), Diagnosis-Intervention Packet (DIP) and Case Mix Index. ResultsThis study proposed a systematic standard framework for rehabilitation medical records, covering key components such as patient demographics, rehabilitation diagnosis, functional assessment, rehabilitation treatment prescriptions, progress evaluations and discharge summaries. The research analyzed the systematic application methods and data standards of ICD-10/ICD-11, ICF and ICHI Beta-3 in the fields of medical record terminology, coding and assessment. Constructing a standardized data structure and data standards for rehabilitation medical records can significantly improve the quality of data reporting based on the medical record summary sheet, thereby enhancing the quality control of rehabilitation services, effectively supporting the optimization of rehabilitation medical insurance payment mechanisms, and contributing to the establishment of rehabilitation medical performance evaluation and payment based on DRG and DIP. ConclusionStructured rehabilitation records and data standardization are crucial tools for quality control in rehabilitation. Systematically applying the three reference classifications of the WHO-FICs, and aligning with national medical record and electronic health record specifications, facilitate the development of a standardized rehabilitation record architecture and core dataset. Standardizing rehabilitation care pathways based on the ICF methodology, and developing ICF- and ICD-11-based rehabilitation assessment tools, auxiliary diagnostic and therapeutic systems, and supporting terminology and coding systems, can effectively enhance the quality of rehabilitation records and enable interoperability and sharing of rehabilitation data with other medical data, ultimately improving the quality and safety of rehabilitation services.

ObjectiveTo investigate the influence of histone deacetylase 3 (HDAC3) on the occurrence, development of psoriasis-like inflammation in mice, and the relative immune mechanisms. MethodsHealthy C57BL/6 mice aged 6-8 weeks were selected and randomly divided into 3 groups: control group (Control), psoriasis model group (IMQ), and HDAC3 inhibitor RGFP966-treated psoriasis model group (IMQ+RGFP966). One day prior to the experiment, the back hair of the mice was shaved. After a one-day stabilization period, the mice in Control group was treated with an equal amount of vaseline, while the mice in IMQ group was treated with imiquimod (62.5 mg/d) applied topically on the back to establish a psoriasis-like inflammation model. The mice in IMQ+RGFP966 group received intervention with a high dose of the HDAC3-selective inhibitor RGFP966 (30 mg/kg) based on the psoriasis-like model. All groups were treated continuously for 5 d, during which psoriasis-like inflammation symptoms (scaling, erythema, skin thickness), body weight, and mental status were observed and recorded, with photographs taken for documentation. After euthanasia, hematoxylin-eosin (HE) staining was used to assess the effect of RGFP966 on the skin tissue structure of the mice, and skin thickness was measured. The mRNA and protein expression levels of HDAC3 in skin tissues were detected using reverse transcription real-time quantitative polymerase chain reaction (RT-qPCR) and Western blot (WB), respectively. Flow cytometry was employed to analyze neutrophils in peripheral blood and lymph nodes, CD4⁺ T lymphocytes, CD8⁺ T lymphocytes in peripheral blood, and IL-17A secretion by peripheral blood CD4⁺ T lymphocytes. Additionally, spleen CD4⁺ T lymphocyte expression of HDAC3, CCR6, CCR8, and IL-17A secretion levels were analyzed. Immunohistochemistry was used to detect the localization and expression levels of HDAC3, IL-17A, and IL-10 in skin tissues. ResultsCompared with the Control group, the IMQ group exhibited significant psoriasis-like inflammation, characterized by erythema, scaling, and skin wrinkling. Compared with the IMQ group, RGFP966 exacerbated psoriasis-like inflammatory symptoms, leading to increased hyperkeratosis. The psoriasis area and severity index (PASI) skin symptom scores were higher in the IMQ group than those in the Control group, and the scores were further elevated in the IMQ+RGFP966 group compared to the IMQ group. Skin thickness measurements showed a trend of IMQ+RGFP966>IMQ>Control. The numbers of neutrophils in the blood and lymph nodes increased sequentially in the Control, IMQ, and IMQ+RGFP966 groups, with a similar trend observed for CD4⁺ and CD8⁺ T lymphocytes in the blood. In skin tissues, compared with the Control group, the mRNA and protein levels of HDAC3 decreased in the IMQ group, but RGFP966 did not further reduce these expressions. HDAC3 was primarily located in the nucleus. Compared with the Control group, the nuclear HDAC3 content decreased in the skin tissues of the IMQ group, and RGFP966 further reduced nuclear HDAC3. Compared with the Control and IMQ groups, RGFP966 treatment decreased HDAC3 expression in splenic CD4⁺ and CD8⁺ T cells. RGFP966 treatment increased the expression of CCR6 and CCR8 in splenic CD4⁺ T cells and enhanced IL-17A secretion by peripheral blood and splenic CD4⁺ T lymphocytes. Additionally, compared with the IMQ group, RGFP966 reduced IL-10 protein levels and upregulated IL-17A expression in skin tissues. ConclusionRGFP966 exacerbates psoriatic-like inflammatory responses by inhibiting HDAC3, increasing the secretion of the cytokine IL-17A, and upregulating the expression of chemokines CCR8 and CCR6.

Aim To explore the effects of Lycium berry seed oil on Nrf2/ARE pathway and oxidative damage in testis of subacute aging rats. Methods Fifty out of 60 male SD rats, aged 8 weeks, were subcutaneously injected with 125 mg • kg"D-galactosidase in the neck for 8 weeks to establish a subacute senescent rat model. The presence of senescent cells was observed using P-galactosidase ((3-gal), while testicular morphology was examined using HE staining. Serum levels of testosterone (testosterone, T), follicle-stimulating hormone ( follicle stimulating hormone, FSH ) , luteinizing hormone ( luteinizing hormone, LH ) , superoxide dis-mutase ( superoxide dismutase, SOD ) , glutathione ( glutathione, GSH) and malondialdehyde ( malondial-dehyde, MDA) were measured through ELISA, and the expressions of factors related to aging, oxidative damage, and the Nrf2/ARE pathway were assessed via immunohistochemical analysis and Western blotting. Results After successfully identifying the model, the morphology of the testis was improved and the intervention of Lycium seed oil led to a down-regulation in the expression of [3-gal and -yH2AX. The serum levels of SOD, GSH, T, and FSH increased while MDA and LH decreased (P 0. 05) . Additionally, there was an up-regulated expression of Nrf2, GCLC, NQOl, and SOD2 proteins in testicular tissue ( P 0. 05 ) and nuclear expression of Nrf2 in sertoli cells. Conclusion Lycium barbarum seed oil may reduce oxidative damage in testes of subacute senescent rats by activating the Nrf2/ARE signaling pathway.

Biliary tract carcinoma （BTC） is a type of gastrointestinal tumor with a low incidence rate and a strong invasive ability， mainly including intrahepatic cholangiocarcinoma （ICC）， extrahepatic cholangiocarcinoma （ECC）， and gallbladder carcinoma （GC）， often accompanied by local progression or distant metastasis. Surgery is often the preferred treatment method for patients with local resectable tumor； however， there is still a high risk of recurrence after radical surgery. Therefore， multiple treatment modalities are often required for BTC patients， including surgical resection， systemic treatment （such as targeted therapy， chemotherapy， and immunotherapy）， and/or a combination of local treatment methods. With the development of the field of BTC， it is critical for surgical oncologists to understand and master the latest surgical strategies and the best patient selection and management systems. In view of the complexity of treatment and the continuous development of diagnosis and treatment techniques， Annals of Surgical Oncology， an authoritative American journal of cancer surgery， recently published the practical diagnosis and treatment guidelines for hepatobiliary tumors， including hepatocellular carcinoma （HCC）， ICC， ECC， and GC， aiming to provide more evidence-based evidence for the clinical management and decision-making of patients with hepatobiliary tumors. Due to the limitations of length and different emphases， this article mainly introduces the recommendations for the evaluation points and clinical treatment of ECC and GC in the guidelines， so as to provide a reference for clinical practice.

The gene GeDRP1E encoding dynamin-related protein 1E in Gastrodia elata was cloned by specific primers which were designed based on the transcriptome data of G. elata. Bioinformatics analysis on GeDRP1E gene was carried out by using ExPASy, ClustalW, MEGA, etc. Positive transgenic Arabidopsis plant and potato minituber were obtained with the genetic transformation system of Arabidopsis and potato. The plant height and seed setting rate of transgenic Arabidopsis, and agronomic characters, such as size, weight and starch content of potato minituber of transgenic potato were tested and analyzed. And GeDRP1E gene function was preliminarily investigated. The results showed that the open reading frame of GeDRP1E gene was 1 899 bp in length and 632 amino acids residues were encoded, with a relative molecular weight of 69.90 kDa and a molecular formula of C₃₀₇₉H₄₉₇₃N₈₈₃O₉₃₃S₁₉. It was predicted that the theoretical isoelectric point was 7.27, the instability coefficient was 43.34, and the average hydrophilicity index was -0.259, which was indicative of an unstable hydrophilic protein. GeDRP1E has no transmembrane structure and signal peptide, and was localized in the cytoplasm. The phylogenetic tree showed that GeDRP1E was highly homologous with DRP1E proteins of other plant species, among which GeDRP1E had the highest homology with DcDRP1E (XP_020689662.1) in Dendrobium candidum, reaching 90.05%. GeDRP1E plant expression vector pCambia1300-35Spro-GeDRP1E was constructed by double digests, and Arabidopsis complementary mutant and potato overexpression strain of GeDRP1E gene were obtained by Agrobacterium-mediated gene transformation. Compared with the Arabidopsis AtDRP1E mutant, the height and seed setting rate of the GeDRP1E complementation mutant were rescued. The minituber of GeDRP1E overexpression potato had larger size, heavier weight and higher starch content, comparing to wild-type potato. It was preliminarily induced that GeDRP1E was involved in mitochondrial morphology regulation, which related to the growth and development of Arabidopsis plants and potato miniature. The research results laid a foundation for further elucidating the molecular mechanisms underlying the growth and development of G. elata tuber development.

The outer membrane composed predominantly of lipopolysaccharide (LPS) is an essential biological barrier for most Gram-negative (G^-) bacteria. Lipopolysaccharide transport protein (Lpt) complex LptDE is responsible for the critical final stage of LPS transport and outer membrane assembly. The structure and function of LptDE are highly conserved in most G^- bacteria but absent in mammalian cells, and thus LptDE complex is regarded as an attractive antibacterial target. In recent 10 years, the deciphering of the three-dimensional structure of LptDE protein facilities the drug discovery based on such "non-enzyme" proteins. Murepavadin, a peptidomimetic compound, was reported to be the first compound able to target LptD, enlightening a new class of antibacterial molecules with novel mechanisms of action. This article is devoted to summarize the molecular characteristics, structure-function of LptDE protein complex and review the development of murepavadin and related peptidomimetic compounds, in order to provide references for relevant researches.

Data analysis models may assist the transmission of traditional Chinese medicine （TCM） experience and clinical diagnosis and treatment， and the possibility of constructing a “data-knowledge” dual-drive model was explored by taking gastric precancerous state as an example. Data-driven is to make clinical decisions around data analysis， and its syndrome-differentiation decision-making research relies on hidden structural models and partially observable Markov decision-making processes to identify the etiology of diseases， syndrome elements， evolution of pathogenesis， and syndrome differentiation protocols； knowledge-driven is to make use of data and information to promote decision-making and action processes， and its syndrome-differentiation decision-making research relies on convolutional neural networks to improve the accuracy of local disease identification and syndrome differentiation. The “data-knowledge” dual-driven model can make up for the shortcomings of single-drive numerical simulation accuracy， and achieve a balance between local disease identification and macroscopic syndrome differentiation. On the basis of previous research， we explored the construction method of diagnostic assisted decision-making platform for gastric precancerous state， and believed that the diagnostic and decision-making ability of doctors can be extended through the assistance of machines and algorithms. Meanwhile， the related research methods were integrated and the core features of gastric precancerous state based on TCM syndrome differentiation and endoscopic pathology diagnosis and prediction were obtained， and the elements of endoscopic pathology recognition based on TCM syndrome differentiation were explored， so as to provide ideas for the in-depth research and innovative application of cutting-edge data analysis technology in the field of intelligent TCM syndrome differentiation.

BACKGROUND:Nucleus pulposus degeneration is an important pathological link of intervertebral disc degeneration.Melatonin has a protective effect on cells through anti-inflammatory and antioxidant pathways,but the effect of melatonin on the nucleus pulposus has been less studied.At present,the emergence of various biological scaffolders provides a new idea for the study of drug-material combinations.OBJECTIVE:To explore whether melatonin can improve the metabolic state of the nucleus pulposus by reducing oxidative stress damage as well as the effect of gelatin methacryloyl(GelMA)microspheres loaded with melatonin on intervertebral disc degeneration in vivo.METHODS:In vitro,melatonin was combined with GelMA solution,and GelMA hydrogel was prepared into microspheres by microfluidic technology to co-culture with nucleus pulposus cells.The cell proliferation activity was detected by cell counting kit-8 assay,the surface morphology of the microspheres was observed under scanning electron microscopy,and the rate of drug release was detected by ultraviolet spectrophotometer.Then,interleukin-1β was used to induce degeneration of the nucleus pulposus.After treatment,the expression levels of aggrecan,type Ⅱ collagen α1,matrix metalloproteinase 13 and a disintegrin and metalloproteinase with thrombospondin motifs-5(ADAMTS5)in the nucleus pulposus were detected by qRT-PCR.In vivo,nucleus pulposus degeneration was induced by puncture.Subsequently,GelMA and GelMA@MT microspheres were injected.After 6 weeks,the specimens were taken for tissue staining,and the changes in tissue morphology were observed under the microscope for histological analysis and scoring.RESULTS AND CONCLUSION:(1)When the GelMA and GelMA@MT microspheres were observed under electron scanning microscope,melatonin binding did not change the morphology and external appearance of the microspheres.Drug release experiments showed that the drug release reached about 80%after 40 days.(2)Cell counting kit-8 assay results showed that both GelMA and GelMA@MT microspheres had no obvious cytotoxicity and promoted the proliferation of nucleus pulposus cells.(3)qRT-PCR results revealed that GelMA@MT microspheres increased the expression of aggrecan and type Ⅰ collagen α1 in the interleukin 1β environment by 42.1%and 27.1%,respectively,and decreased the expression of matrix metalloproteinase 13 and ADAMTS5 by 70.7%and 109.3%,respectively.(4)The level of reactive oxygen species was significantly lower in the interleukin 1β+GelMA@MT group than in the interleukin 1β and interleukin 1β+GelMA groups.(5)Histological staining of the sections showed that melatonin-loaded GelMA microspheres significantly delayed disc degeneration in vivo.(6)These findings indicate that GelMA@MT microspheres made by combining melatonin with GelMA hydrogel have good cytocompatibility in vitro and significantly delay nucleus pulposus degeneration in vitro and in vivo.

BACKGROUND:The imbalance of matrix synthesis and degradation is the main cause of nucleus pulposus degeneration.Small molecule drug Kartogenin(KGN)can restore the balance of matrix synthesis and degradation.Sustained release of KGN using an appropriate drug delivery system is essential for the long-term and effective treatment of KGN.OBJECTIVE:To prepare the injectable hydrogel microspheres by encapsulating KGN with gelatin methacryloyl(GelMA)by microfluidic technology and to investigate the biocompatibility and biological function of nucleus pulposus cells.METHODS:β-Cyclodextrins(β-CD)and KGN were mixed firstly and then mixed with 10%GelMA at a volume of 1:9.Injectable hydrogel microspheres GelMA@β-CD@KGN were prepared by microfluidic technology.The micromorphology of the microspheres was characterized using a scanning electron microscope.The drug release of hydrogel microspheres immersed in PBS within one month was measured.Nucleus pulposus cells were isolated from SD rats and passage 1 cells were cultured in three groups.In the control group,nucleus pulposus cells were cultured separately.In the other two groups,GelMA@β-CD microspheres and GelMA@β-CD@KGN microspheres were co-cultured with nucleus pulposus cells.Cell proliferation was detected by CCK-8 assay and cell survival was detected by live/dead cell staining.Cells were cultured by two complete media with and without interleukin-1β with two kinds of microspheres.mRNA expressions of matrix synthesis and decomposing proteins in nucleus pulposus cells were detected by RT-PCR.RESULTS AND CONCLUSION:(1)Under the scanning electron microscope,the GelMA@β-CD@KGN microspheres after lyophilization were regularly spherical,highly dispersed,uniform in size and full in shape.GelMA@β-CD@KGN microspheres sustained drug release in vitro,reaching 62%of the total drug release at 30 days.(2)Live/dead cell staining showed that GelMA@β-CD@KGN could maintain the activity of nucleus pulposus cells.CCK-8 assay showed that GelMA@β-CD@KGN could promote the proliferation of nucleus pulposus cells.(3)In the complete media with and without interleukin-1β,mRNA expression of aggrecan and type Ⅱ collagen was higher in the GelMA@β-CD@KGN microsphere group than that in the GelMA@β-CD microsphere group(P<0.05,P<0.01);mRNA expression of matrix metalloproteinase 13 and platelet reactive protein disintegrin metallopeptidase 5 was lower than that in the GelMA@β-CD microsphere group(P<0.01).(4)These findings indicate that GelMA@β-CD@KGN microspheres have good biocompatibility and sustained drug release ability.As a drug delivery system,it is a kind of biomaterial with broad application prospects.
